Galaxy S7 Fast Charge & MTP Not Working, Computers Cannot Recognize It!! - Samsung Galaxy S7 Questions and Answers

Hi dear xda users
I have a Samsung Galaxy S7 SM-G930F model and facing a very frustrating issue. The problem began a couple of months ago, when I woke up, the fast charging ability and any USB connection with computer was gone.
The steps that I've tried
1) I have tried it with multiple computers, multiple USB ports and ORIGINAL 2.0A fast wall chargers, can't recognize it,can't fast charge.
2) I have installed ADB drivers and all Samsung drivers, still not recognized,still can't fast charge.
3) I've tried to revert it to stock with stock firmware, stock bootloader and modem, even in Fastboot Download mode, still not recognized.
4) Last thing, I thought it might be the charging port (flex) is broken and I've had it changed with the same new charging flex in front of my eyes with a technician and still can't get it recognized or fast charged.
5) I have changed the settings and tried almost all combinations from the dialer menu *#8800#, still can't!
The device did not contact any water at all and I am beginning to think that motherboard is corrupt somehow.
Another bad news is Samsung Turkey Official Service Centers are denying to repair the devices that you bought from any other country (SHAME ON YOU SAMSUNG!)
They basically won't replace or repair anything with in my phone! (still, it is the same model that they sell in Turkey)
Have anyone faced the similar issues with me?

Only thing I know of is if you have USB debugging on, it prevents some USB functionality until turned off. But if you flashed stock, USB debugging should have reverted to stock.
And yes Samsung warranty doesn't cover grey imports, you have to buy locally.

I've tried almost all possibilities and no, you got me wrong, I am not asking for a warranty covered service, even I say that I am going to pay for it, they won't do it.

Sounds like you've ruled out just about everything apart from the phones USB charging port itself, replace the charging port

You mention charging port "Flex", I assumed by that wording you meant some cable from the port
Well only thing left is the battery and main motherboard really

happened to my old s7 edge and i did all you have done too but no luck. it is some software bug i read soemwhere which only samsung can fix via ota cause our phone cant get detected by pc to flash rom. so all eforts in vain , and i sold the phone in the end. also mine used to get charged in 5-6 hours cause it detecs every cable as usb cable.

I have same problem my phone charging 0-100 6hours but ı install notorious kernel and it takes 3 hours it is better than 6 hours

Thank you for this solution, after I've flashed Notorious Kernel, mine shows 3 hours too! Still can't understand why...

Why? Because you have rooted your phone.

Almost everyone in this forum has a rooted phone, yet this is an issue few have experienced. Rooting might be the first step they took to breaking something, but rooting alone couldn't be the cause otherwise you'd see way more of this.

Keep it on track guys!!!!!

How are we gonna fix this! I'm scared if my phone dies and I can't connect it to a pc..

[Q] [i9023] Water damage - USB won't connect to PC.

Hi there,
My Nexus S (i9023) phone recently fell into a water bucket and I immediately pulled it out.
Not much damage was done to it except of one thing: after I put it in a bag of rice like stated on the internet for overnight, and then plugged it in again to the charger, it seems like something was different.
When I plug the phone to the AC power - phone DOES charge, but nothing else happens.
It doesn't turn on screen and informs "charging", and doesn't have the "charge when phone is off" option anymore. Instead it would just turn the phone on.
Also, when connecting the phone to the computer nothing happens, it's just charging the phone! can't mount USB anymore
I took the phone to a lab which handles these cases. They replaced the USB port and cleaned all the corrosion. They said it's fixed now, and indeed the USB port is new.
But then after coming back home it's still the same.
I'm sick of being dependant on other people and would like to fix it myself.
Any clue which part of my phone was fried? Where can I get it?
Thanks!

Are u rooted?
Try a different ROM. Maybe one ur ur backups.
If it still does connect then it has to be the ROM assuming ur computer has the proper drivers still.
Good luck
Vs Nexus S 4G
Thanks!
Thank you!!!
Problem solved after I loaded one of my backups.
Any explanation to that? even when the phone was turned off it couldn't charge it in off mode and now it can.
How come it's a software issue?
Thanks!
I can only guess that ur ROMs kernel had a "fast charge" option. If so this doesn't allow computer connection. How it got switched to that option... who knows .... maybe the sudden power surge.
If not that, then ... strange things happen when a phone get wet.. the sudden power surge could have changed the power output causing CPU adjustments... who knows.
I'm just happy it worked for u.
I'd recalibrate ur battery asap.
Good luck
Vs Nexus S 4G
Hi, the same thing happened to me, only it wasn't a bucket, it was a pool, and changing the ROM didn't work (I've flashed at least three different ROMs since then, kind of hard when the USB port doesn't work but eh, what can you do).
Also, it's on a Gio, not a Nexus S, but the principle should still be the same, yes?

Hard Brick?

I believe I have a hard brick, but not sure about diagnosis or options. I put my phone on the charger last night, and it was dead this morning. I have been able to get it to boot twice only for it to shut off immediately due to lack of charge. I have plugged the phone into 3 different USB chargers and none of them appear to be charging my phone, however they all work on my Nexus 7. There is no LED on to indicate it is charging as it normally would. I cannot get into recovery or download mode. Any suggestions?
A little background about my specific situation:
I have had my S3 since launch, and have had no issues with it. I have had it rooted since the bootloader was overcome, and have run custom ROMS ever since. Most recently, I have been running CM 11 with the latest nightly being from early Feb. (not sure which date). I have CWM installed, and up til this point, my phone was working fine. I did get occasional random reboots since the latest nightly that I flashed, but the phone remained completely functional.
EDIT: It is not a brick problem, it is a charging issue. I can charge my phone in the car, but not through a wall charger or connected to a pc. When plugging into a pc, it does not register anything at all.

It's possible that your usb port is bad, but try to clean the inner contacts of the port first. You could try to plug into your PC instead of wall charger see if it works. In anycase if it worked with PC, but not wall charger or both, you need to replace the usb board which can be purchase for cheap on Ebay.

Do you have an external battery charger or a spare charged battery? Give it a try and see what happens.

Do you know of someone who has an S3? Perhaps try swapping batteries with a charged one from a friend/associate, or test with a spare from a verizon store. At least then you can rule out a charging/USB charge port/battery issue vs something else

I don't know anyone. I am going to try and seek help at the verizon store, but they seem so useless whenever I go, and I think they will be more motivated to sell me a new phone.
Well I got my phone to work. I pulled the battery off and just cleaned out some of the dust that had collected. I assume it was just not getting a good connection. Thanks for the suggestions though

Turns out, it only worked on my car charger. The problem persists outside of my car. I cannot charge either through a wall outlet or on a USB cord connected to a PC. I have tried 2 instances of each all with their own cables. My car charger works fine though.
Anyone experience a similar problem? I am going to try and wipe and flash a new ROM, hoping that will fix it.

Warranty!!

Hey guys
Im gonna take advantage of my warranty and repair my phone but first i want to know something. I flashed CM11 and then reflashed original firmware. I didn't used any "triangle away" or other software to downdrade to original....just odin. Is there any way that Samsung will know that i used other software? Is there any way to find out if the counter meter changed?
I ask this because i have a bug. If i plug out the charger or USB cable the phone still shows that the cable is pluged in either on USB or charger!!!
Can someone help?
what about bootloader

Try re-flashing stock rom once again.
Otherwise, i don't think it would be that big problem. I've had several visits at service center and the people there were completely dumb ! lol

[Q] inconsistent battery charging - any help?

Hi guys,
Been having issues with charging for the past couple of days. When I plug my phone into the charger it states that it's charging, but nothing really happens. The troubleshooting so far:
Have tested it on multiple different chargers, all having same problem. However, my Nexus7 tablet will charge normally on these chargers, so we can rule out it's charger related.
Tested for differences with the phone switched on or off. When phone is switched off it will charge, but not with the speed it normally does.
Running CM11 Snapshot M9. Did a clean install. Battery does not charge normally (read 1% gain per 20 min) on most stripped down version (without gapps + personal apps)
Looks like it's battery related. But I find it difficult to rule out what's causing my phone to act funny. The weird thing is that sometimes my phone will go for a decent charge, but this happens so randomly that it's hard to find any form of sense in this process. Also, when the phone is on and charging, the battery light will sometimes turn off. But when I activate my phone again, the battery light will bleep on as if nothing happened and everything is functioning normally (which is clearly doesn't).
Does anybody have an idea how I can fix this? Any helpful tips that can point me into the right direction to figure out what's causing this? Many thanks in advance!
did some more testing - can anyone help me out?
After some additional testing I'm fairly sure that it's either battery or chip related:
USB debugging does not work at all (storage is set to MTP). When I open Android File Transfer my Mac will recognise the Nexus 7 tablet, but not the Nexus 5. Debugging is switched on in Developer options.
When I try to use adb or fasboot, my device is not listed either, nor are any commands (directed towards phone) executed through bootloader.
In the about Phone section I went to check the Battery info. It will state correctly that the phone is being charged through AC or USB (depending on wether the device is connected to laptop or charger).
Does anyone have an idea how I can figure out if it's chip or battery related? I desperately want to find this out, because I bought my phone in The States and live in Europe... So in the worst case scenario the phone needs to go back to the US due to bureaucratic policies. Already had to go through this horrible proces half a year ago with a bad NAND chip, really want to avoid the hassle and lose my phone for at least a month. So if it's a battery thing I rather order a new one and replace it myself
Really really hope someone can shed light on this issue, running out of luck and options. Please guys, please :angel:
sounds like the usb connection, physical, is going. if it doesnt charge but randomly will, fastboot nor adb see it, i think its an usb connection issue. i had the same with my nexus one a long time ago, if i wiggled the the connection when it was connected, sometimes i could get it to charge some. fortunately, it isnt an expensive repair, and yours should still be under warranty.

Thanks for the reply, really appreciate it How much you reckon it will cost? Also, can I do this at any decent phone recovery shop? As stated previously, really want to avoid sending the phone back to the US. Once again thanks!

Fast charge not working in s6 after marshmallow (6.0.1) update

I updated my (factory unlocked) S6 to Marshmallow 6.0.1 and for two days it worked just fine. Then suddenly the fast charge stopped working. when i open notifications it says: cable charge, 5 hours until full charge. I tried everything, i have 2 original adaptive fc samsung chargers and none of them works. plus an aukey fast charging external battery, but when i connect my phone it keep saying cable charge. i pushed the usb into the charger, i turned on the fast charging option in settings, tried different cables. then i tried to connect it to my pc, but it doesnt recognizes my phone, and neither does the Mini MicroSD Card Reader that worked just fine before the update. I did a hard reset, but it wont work. im thinking maybe something (hardware) broke in the second day after the update, idk. i remember conecting the phone at night before going to sleep to an iphone cube with the battery at 90%, but that wont explain why my pc doesnt recognise it. I NEED HELP, PLZ
Just a thought: did you enable fast charging option from the battery menu ?
Please read again
it clearly says i turned on the fast charge option in settings
"5 hours until full charge"
something else is wrong here

Why? How do you know? What do you think its the problem?
the weird thing is that when I connect the s6 to the wall charger it pops up the "connected as a media device" that should appear when connecting to a computer. AND when I connect it to the computer it doesnt appear, so I cant move files, etc.
I have the same issue! I know for a fact that it started right after I charged my phone a little on my friend's car charger. I have charged my phones on his charger in the past and have never had issues. It's almost like the phone got scared and locked itself down (stopped transmitting and recieving USB data, therefore not recognizing fast charger or mtp). I have been searching this issue for a while, but have not been able to find a solution. There are lots of people out there that have this problem! I have called Samsung, but they barely even wanted to talk to be because it is the unlocked variant (sm-g920i). Honestly at this point I would be willing to pay them maybe $50 to fix it. It's ridiculous! And I suspect that it is just their dumbass firmware that screwed me over!
I also suspect that is the firmware, but i have searched everywhere and the only ones that could fix it did it by changing the usb port (therefore it was a hardware problem). The ****ty thing is that this phone is too difficult to open, and too dangerous, i dont dare to do it myself, but i neither trust anyone who isnt samsung... so.. i think im just going to sell it and buy anotherone, or idk.. if you can solve the problem please let me know. I'll really appreciate it. (Sorry for bad english)
you might want to try clear both daavik cache and cache.
. I had a similiar problem, that seemed to clear it up.
to clear the dalvik cache i have to root it, and i dont want to in case i have to take it to samsung because maybe if i root it i will loose the warranty. and i already cleared all the other caches like 5 times, i dont know what to do anymore. thank you for the reply, if you know of anything else I can try...
I can confirm that it is not hardware related. I have replaced the board containing the USB port, but am still having the same issue!
And have you found a firmware/software solution to the problem? what's exactly your issue? the same as mine? no fast charge and not connecting to pc?
I also have the same problem, since wiped the device with paper and sometimes back fast loading, however the transfer via USB does not work. I believe it is software problem.
Yesterday I noticed that my data cable connects via download mode by odin, or as may be hardware if odin recognize?
guys,i got a galaxy s6 edge and i had a fast charging issue and i've checked all common solution like changing cables,chargers,even changed the socket but same issue exits my mobile charging in 6 hours and when i go to fast charge option in menu it turned on and at the moment of connecting the cable to automaticly turn off with no choise to turn it on again,any one please knows how so solve??
